bit 5	GPIO5 Pin IO Configuration
	When this bit = 1, GPIO5 is configured as an output. When this bit = 0 (default), GPIO5 is config-
	ured as an input. Note the MD8 pin must be high at the rising edge of RESET# to enable GPIO5,
	otherwise the BLANK# pin is controlled automatically and this bit will have no effect on hardware.
bit 4	GPIO4 Pin IO Configuration
	When this bit = 1, GPIO4 is configured as an output. When this bit = 0 (default), GPIO4 is config-
	ured as an input. Note the MD8 pin must be high at the rising edge of RESET# to enable GPIO4,
	otherwise the DACRD# pin is controlled automatically and this bit will have no effect on hardware.
bit 3	GPIO3 Pin IO Configuration
	When this bit = 1, GPIO3 is configured as an output. When this bit = 0 (default), GPIO3 is config-
	ured as an input. Note the MD[7:6] pins must be properly configured at the rising edge of RESET#
	to enable GPIO3, otherwise the MA9 pin is controlled automatically and this bit will have no effect
	on hardware.
bit 2	GPIO2 Pin IO Configuration
	When this bit = 1, GPIO2 is configured as an output. When this bit = 0 (default), GPIO2 is config-
	ured as an input. Note the MD[7:6] pins must be properly configured at the rising edge of RESET#
	to enable GPIO2, otherwise the MA11 pin is controlled automatically and this bit will have no
	effect on hardware.
bit 1	GPIO1 Pin IO Configuration
	When this bit = 1, GPIO1 is configured as an output. When this bit = 0 (default), GPIO1 is config-
	ured as an input. Note the MD[7:6] pins must be properly configured at the rising edge of RESET#
	to enable GPIO1, otherwise the MA10 pin is controlled automatically and this bit will have no
	effect on hardware.
bit 0	GPIO0 Pin IO Configuration
	When this bit = 1, GPIO0 is configured as an output. When this bit = 0 (default), GPIO0 is config-
	ured as an input.
